Again - thanks for the welcome chrissy and everyone.
tetra - yes and yes. The conference was a multidisciplinary one, but I presented a paper on a topic from my area.
Welcome back, judging from your username I thought you lived in Poland.
greendawn,
I do. I went to Boston and I'm back in Poland now, but also back to JWD. So I'm farther away from most posters now, but back posting. That's why I got a welcome. Confusing? ;-)
